Preheat your oven to 400°F (200°C).
Cut the sausage into slices, peel and cube the sweet potatoes, and chop the broccoli into florets.
Arrange the sausage, sweet potatoes, and broccoli on a large sheet pan in a single layer.
In a small saucepan, melt the butter, sauté the garlic, then stir in honey, soy sauce, vinegar, salt, and pepper. Simmer for 2-3 minutes.
Pour the honey garlic sauce over the arranged ingredients and toss gently.
Roast in the oven for about 25-30 minutes, stirring halfway through.
Garnish with fresh parsley before serving.
